IMPROVEMENT IN FURNACES FOR PITCHING BARRELS, &c.

Specification forming part of Letters Patent No. 128,329, dated June 25, 1872.

Specification describing certain Improvements in Furnace for Pitching Barrels, &c., invented by HENRY SHLAUDEMAN, of Decatur, in the county of Macon and State of Illinois.

My invention relates to an improvement in furnaces for pitching barrels, 85e., previous to filling them with malt or volatile liquids; and consists of a series of curved pipes attached to the furnace; a rod around and outside of said pipes, with suitable hooks to engage with the rims of the barrels to hold them under the mouths of the pipes, A fender is placed between the furnace and the barrels to prevent the outside of them from being` charred from the heat of the furnace. A number of barrels can be heated at the same time; the whole so arranged that the pitch when melted (when barrels are being repitched) shall run down under the mouth of the pipe and prevent the staves from charring. The second part of my'invention consists of two pipes provided with a valve and leading into the furnace from a blower, one of the pipes below and the other above the fuel, by which arrangement there is a saving of fuel, and the furnace Vis not liable to become choked with elinkers.

Figure 1 is an elevation of a barrelpitching furnace embodying my invention. Fig. 2 is a plan of the same; Fig. 3, a sectional elevation; and Fig..4, a plan of valve.

A is the furnace. D D are pipes formed, as shown in the drawing, and attached to the furnace. At the outer end of said pipes are small pipes d d that tit in the bung-hole of the barrel. F is a rod fastened to the outside of the pipes D D, as shown at ff. On this rod are suspended and slide the hooks e e, which engage with the rim of the barrel E and hold it under the pipe. G is the fender placed around the furnace to prevent the outside of the barrels from being charred from the heat of the furnace. By this arrangement a number of barrels can be heated at the same time. The table ordinarily used with devices to raise and lower for diiferentsized barrels is dispensed with. The pitch that is in the barrel (when one is being repitched) as it melts runs down under the end of the pipe d, so that the staves will not receive the full force of the blast, as where a table is used to support the barrel and a horizontal pipe attached to the furnace the force of the blast melts the pitch opposite the pipe and chars the stave's before the barrel is thoroughly heated. H is a large curved pipe that can be attached to the top ofthe furnace to be used in pitching large casks. The pipes d d can be closed when this pipe is used, and viceversa, a lid, t', covering the opening I in the top of the furnace, and through which openin-g fuel is fed to the furnace. B is the blower. b is a pipe leading from the blower to the furnace and bifurcated, as shown at b1 b2. The pipe b1 leads into the ash-box and below the grate-bars, and the pipe b2 into the `furnace and above the fuel. This pipe has a valve, O, to eut ofi the air from going above the fuel, and direct it all in the pipe b1 when the iire is being started, after which open the valve and admit the air through the pipebz.

By this arrangement of the pipes, leading both below and above the fire, more hot air is furnished with the salue amount of fuel than if a single pipe leading either above or below the fire is used, and the furnace cannot become clogged up with cinders.

I know that in barrel-pitching apparatus pipes leading either above or below the grate have been used.

I claim as my invention- 1. The curved pipes D D, rod F, hooks e e, and fender G, in combination with the furnace A, substantially as shown and described, and for the purpose set forth.

2. The combination of the pipes b b1 b2 and valve O with the furnace A and blower B, substantially as shown and described, and for the purpose set forth.

HENRY SHLAUDEMAN.
